stonks-cli v0.6.3

Added

• New STALE session label and badge for prices that the upstream data
  source is serving from a prior trading day while the exchange should
  be trading live. Affected rows render -- for the daily change
  rather than a misleading 0.00, and the Last Price column shows a
  STALE badge so the value is clearly flagged as non-live.

Fixed

• Non-US tickers (e.g. CHIP.PA, VUAA.L, IBCJ.DE) no longer show a
  spurious 0.00 daily change during European morning hours. Yahoo's
  one-day batch endpoint silently drops those tickers when today's bar
  hasn't been published yet; the fetcher now uses a 5-day window and
  flags the returned prior-day bar as STALE.
• NYSE / NASDAQ pre- and post-market windows are now bounded by the
  real 04:00 / 20:00 ET hours, so viewing the app in the dead of night
  no longer labels US rows as STALE; they correctly render CLS
  instead.
• Price history charts no longer fail to plot when yfinance occasionally
  returns NaN / inf values mid-series.

Changed

• yfinance dependency pinned to >=1.3.0,<2 (was >=1.2.0,<2).
